I finished the game recently as Jill, I never did play again as Chris and now moved on to RE2, again this might be a single playthrough. I think you have the main story down, so unless you are looking for different endings, just move on. My first attempt I was killing all the zombies and ruined myself before even leaving the mansion. I ended up restarting after 9 hours of play time. If you are looking for the best challenge though, after completing the game it should have unlocked an even harder game mode for you to try. I have too many games to replay some for different endings
